🌍 Travel & Culture

Travel tools cover the practical numbers of a trip: currency conversion, time zones and the date line, packing weight, flight times, fuel and distance, and temperature conversion for weather and cooking abroad. There are also phrase guides and customs references for common destinations. Currency rates update from a public feed, and the pages say so, because rates move. Everything else is calculated from fixed definitions and conventions. Each page explains the method and gives a worked example. No booking, no accounts and no tracking: the calculators run in your browser and you take the answers with you. The travel pages combine the numbers with practical context such as typical tipping customs and luggage limits, so the figures sit next to the advice that uses them.
